IMPROVEMENT- IN LAMPS.

Specification forming part of Letters Patent N0. 135749, dated February 11, 1873.

open, so as t0 remain cool, und the lower encL of the chimney resting upon the supportingbase renders it unnecessary so employ a springedge arou nd the draft-distributer, 1:0 c1ose the chimney a1; this point by contact With the interior of t-he glass.

In the drawing, Figure 1 is a plan of the burner, and Fig. 2 is a vertieal seetioh of the same with the movable defleotor detaohed.

Tho wick-tube a, body b, ratchet or wickraiser c, and the eap d for the same are of usua1 oharacter. The perforated air-distributer e is sustained near the upper end of the wich-Bube, and over the szune is the removable eone or deflectorf With tongues 11 entering mortises in the air-distributer, similar to that in the patent 0f B. F. Adams, 106,303. The edges of the airdistributer are prolonged downward 518 The air-distributer is V a cone, h, and a1: the botton1 is the chimneysupporting fiango k. Openings ab r a1low air to pass in between the ohimney and cone h in a regulated quantity. The supports l, extending from'the ratchet-case to the air-distributer e, Support the 1atter, and such supports extend outwardly andupwardly, formin g the chimneyholding springs s.

It will now be apparent that the base of the uhimney resting upon the flange k renders unnecessary any peripheral springs aronnd the aindistributer to come in oontaot with the interior of the chirnney and interoept the draft, thus more easilyaccomxnodating differentsizes of chimney, and that ab the same time the interior of the bu1"ner blow the aindistribnter is open and will remain cooler than in those cases where the air-distributer is near the lower end -of the eone.

I ela-im as my invention- The air-distributer near the upper end of the wick-tube, and the defleetor resting upon the same, in combination with the oone h, ohin1- ney-supporting flange k, and spring chimneyolamps s, substantially as and for the purposes Set forth.
